IMPROVEMENT IN CAR-AXLE BOXES.

Specication forming part of Letters Patent No. 178,723, dated J une 13,1876; application filed December 6, 1875.

To all whom it muy concern:

Be it known that I, JOHN M. BRosIUs, of Richmond, in the county ofHenricoand State of Virginia, have invented a new and Iniproved ltailwayOar Truck and Box; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawing, forming a part of this specification, in which-Figures l and 3 are transverse vertical sections; Figs. 2 and 4., planviews.r

The invention consists in extending out the end of the upper section ofaxle-box, and making this extension detachable, so as to furnishconvenient access to the space within and allow the brass to bereplaced; in applying to one side of box an inclined spout, and makingan excision on side face of brass, to allow the lubricant to be pouredinto the box, so as to ,easily reach the packing, and also the insertionof packing; in the employment of shouldered standards on the corners ofbox to support the brass above the bottom and allow ample space for thepacking; in using two overlapping adjustable wedges in each box forbringing the'brasses, as they wear, in proper juxtapostion to thejournals; and in making the bottom section in one piece, and with amedian recess, to envelop half the two journals, so as to hold the axlemore steadily and prevent deflection.

A A represent a car-truck, having the inner cross-pieces c c secured tothe outer pieces A, and between said cross-pieces and the pieces A areplaced the short pieces a a. B represents the bearings secured by strapsO on the pieces A, and D the axles journaled in them. These axlesaredoweled together at their inner ends and journaled in boxes E. Thusfar there is nothing on which I propose to secure protection in thisapplication. I make the box E on the upper section with an extension, F,which is bolted through lianges .cf to the main body. This detachableextension is added to the upper section for the purpose of giving readyadmission to the space used for the brasses, so that the latter may beentered or removed with facility and convenience. I also make a spout,G, on the lower section, having the incline g, and a correspondingexcision, h, onthe side of brass H, so that the oil may be readilyapplied and flow down to saturate the porous packing under the brass.The lubricant, having saturated the packing, is gradually trasferred bycapillary attraction, through brass-holes h', to the journal. Thisvspout is covered by a door, gf, which may be hinged to upper section orvsecured in any other suitable manner.

In order to afford proper space in the box for the reception of adequatepacking, I place at the corners (and they may be placed at other points,though they are not necessary) the'vertical standards K, havingshoulders 7c,

-all placed at the same height, so as to support the brass at aconsiderable elevation above the bottom of box.

In order to take up Wear upon the brasses,

I use two overlapping wedges, L L, having closed slot l and open endslot l', the former being a passage for the lubricant, and the latter toreceive the head and neck of a bolt, M. On the latters end is a thread,by which nuts N are adjusted to draw the wedges farther down in the box,and thus keep the brasses and journals in proper alignment.

The .brass heretofore had a median recess in the upper section toreceive a flange on journal; but I find that by making a similar recessin the lower section, and making that section in one piece, there ismore steadiness imparted and less deflection of the axle.

Having thus described my invention, what I claim as new isl. Anextension, F, clamped detachably to the upper s ection of a car-axlebox, as shown and described, to enable the brasses to be easily removedand replaced.

2. The combination of spout G, having incline g, and correspondingexcision on the brass, as and for the purpose set forth.

3. The combination, with an axle-box, ofthe 4corner standards K, havingshoulders lc at the same altitude, as and for the purpose specilied.

4. The combination of slotted overlapping wedges L L andadjusting-screws M with the axle-box, as and for the purpose set forth.

5. A brass made in one piece, and having a median recess, 71.', in lowersection, combined with both journals, as and for the purpose specified.

The above specification of my invention signed by me this 3d day ofDecember, A. D.

JOHN M. BROSIUS.
